Need Unit and Integration Tests for Nodejs/React Frontend

[00hello]

In particular, for WebGL -> Check Deck.gl for examples.

This will help prevent current problem in tauri-apps feature branch where the map is not displaying in the production build

[00hello]

Some documentation on Deck.gl's testing system.

1. How Testing Layers and Applications Works (website docs)
2. How to run tests (repo docs)

See also Contributing docs ...

To run the test suite, you may need to install additional dependencies (verified on Ubuntu LTS):
headless-gl dependencies for the Node tests
puppeteer dependencies for the integration tests

Verify that everything works by running yarn test.
